Sium suave

Sium suave, also widely known as water parsnip, is a wildflower native to parts of the northern hemisphere and thriving in primarily wetland habitats. Sium suave belongs to the carrot family, Apiaceae. Water parsnip blooms from July to August and creates many small white flowers with umbel inflorescences. Sium suave resembles a few quite poisonous plants, and consumption should be avoided. ==Description==

The shape and size of the leaves depends on the environment in which S. suave grows. Basal rosette leaves form on moist ground at around 3.8 cm long, and in shallow water they grow in clusters of aquatic leaves. ==Taxonomy==

Sium suave is a member of the order Apiales and the family Apiaceae, the celery, carrot and parsley family (also known as Umbelliferae). This family contains about 445 genera and about 3540 species. Some distinctive characteristics of this family include compound leaf, simple or compound umbel inflorescence containing many small flowers, 2 styles, 2-carpellate ovary, and a schizocarp fruit that splits into 2 mericarps. This species belongs to the genus Sium which is made up of about 9 species. Species in Sium are all perennial herbs of the northern hemisphere. The diploid number of chromosomes for Suim suave is 22. The Kutenai call water parsnip nakhankam (Ktunaxa: naq̓an̓kam). Sium suave (from the Latin sium, the Latinization of Greek sion, meaning "water parsley," and suâvis, meaning "sweet."), the hemlock waterparsnip or water parsnip, is a herb native to parts of Canada, Asia, and North America. Synonyms for S. suave include Sium cicutifolium Schrank, Sium floridanum Small, Sium suave Walter var. floridanum (Small) C.F. Reed, Apium cicutifolia (J.F.Gmel.) Benth. & Hook.f. ex F.B.Forbes & Hemsl., Cicuta dahurica Fisch. ex Schultz, Sium cicutifolium Schrenk, Sium formosanum Hayata, and Sium nipponicum Maxim. According to a molecular phylogeny created with maximum parsimony heuristic searches using a 59-sequence data set of Sium s.l., Helosciadium, Cryptotaenia, and outgroups, the sister groups of S. suave are Sium medium found in Central Asia and Sium latifolium found in Western Europe, Eastern Europe, and Western Asia. ==Distribution and habitat==

Sium suave grows in wetland habitats (sandy and non-sandy). These wetland habits include wet prairies, bottoms of seeps, low areas along springs, soggy thickets, swamps, borders and shallow water of ponds, marshes, and ditches. It is native to both North America and Asia in Canada, the United States, Japan, Russian Federation, South Korea, and China. ==Uses==

Extreme caution should be practiced when using this plant for food because it resembles the very poisonous Cicuta maculata (Spotted Water Hemlock). Edible parts of Sium suave include the root in the spring and fall, either raw or cooked; it has a nutty flavor. The leaves are also sometimes used for condiments such as relish. Crushed water parsnip roots have also been used as an analgesic (pain reliever) in cases of broken limbs. ==Cultivation==

Water parsnip should be grown in wet mucky soil / sand or in standing water up to an inch and a half deep. It also prefers partial to full sun. In the presence of added N03-N to the ground, water parsnip shows increased production. ==Faunal associations==

These flowers attract a wide variety of insects. While most insects are attracted to the nectar of the flower, bees seek both their nectar and pollen. These include 21 species of bees, 73 species of flies, 91 species of wasps,4 species of plant bugs, 5 species of butterflies, and 19 species of beetles. The stems and leaves of this plant are toxic to livestock. ==References==
